SHADE-HOLDER.

Application filed April'SO, 1917. Serial Nyo. 165,347.

To all whom t mayy concern.'

Be it known that I, JOHN BESWANQER, a citizen of the United States of America, residing in the city of Steubenville, county of Jefferson, State of` Ohio, 'have invented certain new and useful Improvements inShade- Holders, of which the following is a speciiication. A

The modern system of illumination involves the lextensive use of suspended shade bowlslandreflectors of considerable size .and weight. 'These have been supported by various means as frames., tripods and 'the like some of which are expensive and, all of which are more or less inconvenient to use. Further, their use, particularly those which clamp the shade and those the use of which involves the `drilling .of holes in the glass have the disadvantage that 'frequent breakage results.

' The present invention relates to a support shown iny the form of -three-arrivi suspension or ytripod `which is cheap, convenient and almost automatic in its operation and can be used without involving any vvdanger of breaking the reflector shade bowloracorn with which it may be used. It is applicable to the-type having an inwardly turned flange at the upper edge which is preferably integral with the shade butmaybe otherwise arranged. Inthis support, the tension members, wires or arms of the tripod which may be three or more in number, are arranged so that seen in` plan they appear to be radial and their outer ends hook under the inwardly turned flange on the shade, the radius of the ends of the arms or `fingers being greater `than thatof ythe inner edge of the flange. Part of the ytension members are made rigid vand the remainder have the end yportion which is hooked under the shade flange hinged so that it may be swung upward reducing the radius. The hinged joint is of the jack-knife type so that when the hinged member or finger is pulled down it becomes rigid' when in or near the horizontal position. While there may be any number of such arms, part ymade rigid and the re mainder with a hinged end, in the present instance I use three armaftwo rigid and. one

y.Provided with the hinged end or linger. To

. 'apply to the shade, Vthe two rigid ends or fingers are hooked under the flange and the shadev is swung upward bringing thev portion of the flange beneath the hinged finger upward against the finger swinging it upf ward and inward so that the flange passes it. Then the `iiange is caught over the end of the linger and the shade moved downto horizontal or level position when the finger yis straightened out inthe horizontal or rigid position, and, thus increasing the radius of the tripod, the shade is locked4 in position kwith the flange bearing on the ends of the tripod arms.

yIn 'the accompanying drawing I have illustrated a lighting finiture and shade bowl in ,connectionV Vwith which is shown a threearm support or tripod constructed in accordance with my invention. l y

` In the drawing, Figure l is an elevation; and Y Fig. 2 isa plan of the shade bowl and support, etc. y y n Fig. 3 shows the detail structure of the jointed supporting arm.

'Referring to the drawing by numerals, I

`have illustrated the .usual lamp socket l yshCWVll in Fig. l as provided with an upper `shade holder 2 and an upper shade 3. To the lower portion of the outer shell Vof the socket I have secured the upper ends of three pendant supporting wires or arms 4:, 4 and 4'. In the form of the invention shown, the upper ends of these arms are placed inside the outer shell 5 of `the socket and riveted 'thereto but they may be soldered or iformed integral or otherwise secu-redy within the .scope of my invention. Each of these supporting wires or arms ,4: extends downward from the upper end with an outward swing or curve whichin the form of the invention shown becomes sharper near the bottom bringing the lower 'ends or lingers 6 into horizontal yor near y'horizontal position. The exact form of these armsv or supporting wires may of course be widely' varied within the scope of my invention,the object being to provide aplural-ity of hooks, arms or .fingers which as seen in plan extend outward radially and which are adapted to engage the inwardly turned fiange i of va shade vbowl from be- `or more of, said arms, of a hinged finger in place 'of the usual rigid hoolr or finger, the hinge being-of the variety which may be termed the knife-blade type which permits the finger to bend upward but holds it rigidly in horizontal position when downward force is applied to the end of the nger, such force being ordinarily due to the weight of the shade'bowl suspended thereon, the finger being automatic in its action as hereinafter described.

The construction of the joint indicated by reference character 8, the pivoted member being indicated by reference Vcharacter 9, is illustrated most clearly in Fig. '2. As shown, the inner or butt end of the pivoted member is reduced forming an outwardly'and downwardly inclined shoulder 10 and the end of the reduced portion at 11 is inclined in the opposite direction, z'. e., downwardly and inwardly. rihe end of the stationary portion of the wire or finger e is correspondingly shouldered and provided with corresponding, preferably inclined contacting surfaces 12 and 13. The pivot 14 passes through the two reduced portions 15 and 16 near their centers. lt will thus be apparent that by pushing the pivoted member 9 upward the surfaces 10 and 12 and 11 and 13 are thrown out of contact and the pivoted member swings freely, and when it is brought tothe horizontal position, the surface 11 is brought into contact with the surface of the stationary member at 13 and the surface 10 is brought into contact with the surface 12 of the stationary member and the motion is arrested with the pivoted member in or near horizontal position. lt is also apparent that when the linger is swung up, the radius at its end from the axis of the fixture is reduced and when down it is increased. Y

In operation, the flange of the shade bowl 7 is first hooked over the lower ends 6, 6 of the two stationary fingers 17 and 18. Then the flange is pressed from beneath against the pivoted member 9 of the other linger (L causing it to swing up.

ln this way the radius swung to the ends of the fingers is reduced and theflange ,7 passes up by the piyoted member; the shade v'upward as before.

regar?? bowl is then moved slightly to one side causing itto engage the pivoted member from above and is then drawn down swinging the pivoted member to a horizontal position when the radius of the lower ngers is increased becoming greaterthan the radius of the inner edge of the flangek Teo-that the shade bowl is locked in position and can only be removed by swinging the member 9 This may be accomplished byv pushing the shade bowl'up when contact of thev bowl with they end of the finger will swing the pivoted member into the vertical position as shown in Fig. 1 when the radiusv at the ends ofthe fingers is so reduced that the shade bowl may be removed, the inner edge of the flange passing the ends of the ngers.

The added convenience` of such a device over the various supports known to the artmust be recognized. lt is merely necessary to hook the shade howl over the two rigid fingers, push it up by the pivoted 'end and then draw it down when it immediately becomes locked, whereas in the majority at least of the other devices it is necessary for the operator to climb to the level of the fixture whatever that is and usually manipulate the mechanism from both ends while the one described can be easily operated without touching it, merely manipulating and supporting the shade bowl as described.

l have thus described my invention speciiically and in detail inv order thatits nature and operation may befully understood; however, the specific terms herein are used descriptively rather vthan in their limiting sense and the scope of the invention isdefined inthe claims.

l claim-` f 1. ln combination in a lighting fixture, a depending shade with an inwardly disposed flange, fingers extending radially of the fixture as seen inV plan, the fingers extending under the flange on the shade, one of the fingers being piv'oted and adapted to be bent upward from horizontal position, but rigid in horizontal position when downward force is applied.

2. ln combination in a lighting fixture, a depending' shade with an inwardly disposed flange, fingers extending radially of the fix-l ture as seen in plan, the fingers extending under the flange on the shade, one of the fingers being pivoted with a knife blade joint and adapted to be bent upward from horizontal position but rigid in horizontal position when downward force is applied.

3. ln combination in a lighting fixture, a depending shade withan inwardly disposed flange, supporting arms with fingers extending outward substantially radially of the fixture as seen in plan, the fingers extending under the flange on the shade, one of the fingersV being pivoted `With ay knife blade drawn down to a horizontal position Where joint so that the radius'at the endsof the it is locked. l0
